Thumbnail issue after migration from Alfresco 3.2 to 3.3

[kma]

Hi,

After migration from Alfresco 3.2 to 3.3, it is not possible to read thumbnails generated on Alfresco 3.2.
The following call return 0 nodes:

List<NodeRef> thumbnails = thumbnailService.getThumbnails(nodeRef, ContentModel.PROP_CONTENT, null, null);
‍‍‍

As far as I can see, it is because the aspect 'rn:renditioned' is missing,
by adding this aspect like this:

if (nodeService.hasAspect(nodeRef, ContentModel.ASPECT_THUMBNAILED)) {
   if (!nodeService.hasAspect(nodeRef, RenditionModel.ASPECT_RENDITIONED)) {
      nodeService.addAspect(nodeRef, RenditionModel.ASPECT_RENDITIONED, null);
   }
}
‍‍‍‍‍‍‍

it  works.

Is this the correct way to fix it ?


Thanks,
Karsten

No, thanks for link.

I have tried it now but I don't think it will do the job.
The migration code does only handle the 'thumbnail' type,
it does not do anything with the parent.
To read the thumbnails it is required that
the parent has the RenditionModel.ASPECT_RENDITIONED.

I think there is a migration problem or ?

Thanks,
